Function createEncapsulatingRegex

Builds a regex that matches a string between two provided strings. Supports regex as boundaries as well.

Remarks

The function accepts either strings or regular expressions as the left and right patterns. If a string is provided, it will be escaped to form a valid regular expression. The function also accepts an optional flags parameter to specify regular expression flags.

Example

const regex = createEncapsulatingRegex(/a/, /b/)
'abc'.match(regex)?.groups?.mid // 'c'
